WHAT THE TEST MEASURES
About This Assessment
Blood Donation Eligibility Quiz - Symptoms and Signs
This free, no-sign-up, 15-question self-check helps you organize factors that blood donation staff commonly review, including how you feel today, medical history, treatments, travel, and possible blood exposures. It cannot confirm eligibility or replace a blood center’s screening, because rules vary by location and donation type. Contact the center before attending if anything is unclear, and do not stop prescribed medicine to donate. For chest pain, severe breathing trouble, fainting, heavy bleeding, or other severe symptoms, seek urgent medical care instead of donating.
